Homeland Security Update
Beginning June 30, all NOAA Weather Radio Stations in the United States will have begun using the expanded Emergency Alert System (EAS) hazard code list.

Broadcasts now will include hazard information relating to local emergencies, terrorism, nuclear incidents, 911 outages and abducted children, in addition to traditional weather and marine advisories.

ISS ALERT AM (fixed, networkable) and RoadRunnR (portable) advisory radio products have the exclusive ability to key selectively on all 53 hazard codes, on a county-by-county basis, and interrupt regular broadcasts with the latest advisories and special messages from local emergency managers.

ISS stations receive all the National Oceanic and Atmospheric Association (NOAA) event codes and rebroadcast associated alert messages to targeted counties over local AM frequencies. This includes, for example, any child abductions in the states and localities using the AMBER Plan, shelter in place, hazardous material, earthquake, fire, dust storm, nuclear/radiation, volcanic and marine/coastal alerts.

ISS specific-area radio systems are the only ones to have these enhanced notification functions. The ISS receiver will be continuously upgraded to decipher any new national alert codes, if they are developed.

Though most of the automatic warnings involve pure weather, others could involve more. In 2001, the FCC added 21 new codes to the EAS-alert mix. For example, people in coastal communities were given notification codes for coastal flooding, tropical storms and special marine warnings. People in mountainous areas have new notifications for avalanches, earthquakes and volcano eruptions. Residents near industrial plants can now receive HAZMAT notifications. Here are a few other new EAS alert codes:
  • Local or civil danger emergencies.
  • 911-telephone outages.
  • Law-enforcement emergencies. 

A notification of a terrorism threat or act could involve a number of these EAS event codes.

How do ISS systems know which messages to broadcast in a given area? The systems programmed with Specific Area Message Encoding (SAME) protocols to allow targeted broadcasts within each station's range. Stations can be networked/synchronized to cover large counties.
